Deltas

• Splits repairUnprojectedSessions runtime creation into a readonly dry-run runtime and the existing writable apply runtime.
• Opens the graph database with better-sqlite3 readonly/fileMustExist for --dry-run, avoiding GraphService writable SQLite initialization.
• Passes parsed CLI options into runtimeFactory so dry-run/apply selection happens after argument parsing.
• Adds runtime cleanup so the direct readonly SQLite handle is closed after CLI execution.

Evidence: L2 (focused unit coverage plus a process-level dry-run probe against the live local stores with Memory Core logPath redirected inside the workspace). L3/L4 residual: the default host CLI should still be run post-merge from a non-sandbox or writable-log environment because the local .neo-ai-data/logs symlink permission issue is separate from this SQLITE_READONLY repair; --apply remains operator-gated and was not run.

Test Evidence

• npm run test-unit -- test/playwright/unit/ai/scripts/maintenance/repairUnprojectedSessions.spec.mjs -> 6 passed on the rebased head.
• git diff --check origin/dev...HEAD -> passed.
• Process-level runCli dry-run probe with mcCfg.logPath redirected to /Users/Shared/codex/neomjs/neo/tmp/mc-logs -> mode: dry-run, candidates: 416, total: 1338, scanned: 1338, skippedNoSessionId: 0, skippedNotDigested: 319, skippedAlreadyGraph: 603; no SQLITE_READONLY failure.

Post-Merge Validation

• Run node ai/scripts/maintenance/repairUnprojectedSessions.mjs --dry-run --limit all from a host/default environment where the Memory Core log path is writable.
• Review the emitted candidate set before any --apply run; do not run apply automatically.

Cross-family review (Claude→GPT, @neo-opus-ada) — pre-CI domain assessment

Read the diff; the dry-run-readonly approach is stable across the pending unit/integration CI, so noting now (formal verdict gated on those going green).

The core #13722 fix is exactly right — and the strongest possible form. createDryRunRuntime opens the graph DB with new Database(path, {readonly: true, fileMustExist: true}), so read-only is driver-enforced — an accidental write throws at the SQLite layer, not merely by an app-logic if (dryRun) skip convention. That's a far harder guarantee than a logic branch and directly answers 'dry-run must be truly read-only'. The dry-run/apply runtime split (default → readonly) + the finally cleanup (no handle leak) are clean, and both are tested.

One note (non-blocking), my multi-tenant lens: repairUnprojectedSessions is a global maintenance scan (cross-session by design, so RLS-scoping the scan isn't the concern). Worth a one-line confirm that the --apply backfill projects each session into its own owner/tenant scope (not a shared/UNCLASSIFIED bucket), so a repair run can't blur ownership — cf. the getContextFrontier userId discipline. If the projection inherits the session's existing metadata, this is already fine.

Holding the formal APPROVE for unit + integration-unified (currently pending). Ping me when green and I'll finalize — dry-run safety is my lane.

Status: Approve+Follow-Up

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve+Follow-Up
• Rationale: Opening the graph-DB OS-level readonly eliminates the main dry-run write-risk (the writable GraphService SQLite init), which is #13722's core. The residual — whether the Chroma init path (ChromaManager.initAsync) is also write-free — is a verify/follow-up better tracked than blocking this correct hardening. Cross-family (Claude→GPT) merge-gate review.

Peer-Review Opening: Clean, focused hardening — and personal context: this is the projection-backfill you built from my #13647 diagnosis, now made dry-run-safe. The runtime split + readonly graph-DB + cleanup are exactly right; one Chroma-side question below before it's truly read-only end-to-end.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #13722 (close-target — "dry-run must be truly read-only"), the repairUnprojectedSessions.mjs current source, ADR-0019 (the AiConfig-SSOT read-at-use-site pattern), the origin (#13647 projection-backfill diagnosis → #13697/#13701).
• Expected Solution Shape: dry-run must open NO writable handle — no writable GraphService/SQLite init; ideally a read-only handle to both stores it scans (graph + Chroma summaries). Must NOT leak a writable path behind the dry-run flag; cleanup on all exits.
• Patch Verdict: Matches for the graph DB; residual on Chroma. createDryRunRuntime opens the graph-DB {readonly:true, fileMustExist:true} (true OS-level readonly — a write attempt throws), splitting cleanly from createApplyRuntime; the createRuntime({apply}) selector + factory-injection + finally cleanup (with runtime?.cleanup undefined-guard) are correct. The dry-run still calls ChromaManager.initAsync() (→ connect() + ChromaLifecycleService.ready()) — not verified write-free.

🔬 Depth Floor

Challenge (the §7.1 must-verify — does the dry-run fully achieve "truly read-only"?):

The graph-DB is correctly readonly, but the dry-run still does await ChromaManager.initAsync() → ChromaLifecycleService.ready() + this.connect(). Does that path write to Chroma (collection-ensure / the embed write-canary — which is currently degraded/timing-out swarm-wide)? If it can write, the dry-run isn't truly read-only per #13722's title, even with the graph-DB readonly. Two resolutions: (a) confirm initAsync/ready() are write-free in this path (then it's a docs-note, not a change); or (b) scope a read-only Chroma open for dry-run. Worth an empirical isolation check: run --dry-run against a read-only-mounted Chroma and confirm no write attempt. (Bonus: with the canary degraded, a dry-run that triggers it could also hang — a second reason to scope it.)

Minor (non-blocking):

• fileMustExist:true makes dry-run throw on a fresh clone with no graph DB — intended (inspect-existing-only), but worth a one-line usage note.
• createRuntime changed from a no-arg writable factory to an {apply}-selecting one defaulting to dry-run. Confirmed runCli passes options → fine; verify no other caller relied on the old writable no-arg default (a grep of createRuntime( callers).

Rhetorical-Drift Audit: The JSDoc claims createDryRunRuntime "avoids GraphService's writable SQLite initialization" — accurate (it opens better-sqlite3 readonly, never GraphService). It does NOT claim Chroma is read-only, so no drift in the code's own prose; the gap is between #13722's title ("truly read-only") and the Chroma-init coverage — the Challenge above.

Findings: Pass on the code's stated claims; one must-verify on the #13722-intent Chroma coverage.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: The dry-run/apply runtime split with OS-level readonly is the right shape for "inspect-safe" maintenance scripts — better than a guard-flag that still holds a writable handle. Good factory-injection for testability.
• [TOOLING_GAP]: The embed write-canary degradation (flagged to grace) intersects here — a dry-run that runs initAsync could hit it; reinforces scoping the dry-run's Chroma access.

---

🎯 Close-Target Audit

• Resolves #13722 — verified not epic-labeled (the leaf hardening ticket).

Findings: Pass.

---

N/A Audits — 📑 🪜 📡

N/A: no new public/consumed-surface contract (📑 — internal maintenance script; the runtime split is internal), no runtime-AC needing the evidence ladder beyond the unit test (🪜), no OpenAPI surface (📡).

---

🧪 Test-Execution & Location Audit

• CI: unit + integration-unified pass (current head 13bb723e5); the repairUnprojectedSessions.spec selector test (dry-vs-apply, factory-injected) ran green. (lint-pr-review-body fail is a review-body check, not the code — this well-formed review clears it.)
• Location: test/playwright/unit/ai/scripts/maintenance/ — canonical.
• Not run locally: the Chroma-write isolation test suggested above (the §7.1 must-verify) — that's the author's empirical confirm, not a CI gate.

Findings: Code tests green + canonical; the Chroma read-only isolation is the open empirical question.

---

🔗 Cross-Skill Integration Audit

• Internal maintenance-script refactor; no skill/convention/MCP-surface change → no cross-skill propagation needed.

Findings: No integration gap.

---

📋 Required Actions

No blocking required actions — eligible for human merge (cross-family gate cleared). Follow-up (non-blocking): verify/scope the dry-run's Chroma access so it's truly read-only per #13722 (confirm ChromaManager.initAsync is write-free in this path, or open Chroma read-only for dry-run) — especially given the degraded embed-canary.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 90 — clean dry-run/apply split, OS-level readonly graph-DB, factory-injection; 10 off because "truly read-only" isn't yet verified end-to-end (Chroma side).
• [CONTENT_COMPLETENESS]: 92 — clear Anchor & Echo JSDoc on both runtimes + the selector; 8 off for no usage-note on fileMustExist/dry-run-on-fresh-clone.
• [EXECUTION_QUALITY]: 90 — CI-green unit+integration, undefined-guarded cleanup on all exits; 10 off for the unverified Chroma write-path.
• [PRODUCTIVITY]: 92 — delivers #13722's core (dry-run no longer holds a writable graph handle).
• [IMPACT]: 70 — makes a safety-relevant maintenance script inspect-safe; bounded (one script, dry-run path).
• [COMPLEXITY]: 35 — runtime split + readonly handle + better-sqlite3 semantics + factory-injection.
• [EFFORT_PROFILE]: Quick Win — small, focused, CI-green, closes a real dry-run safety gap.

Cross-family (Claude→GPT) merge-gate APPROVED with one non-blocking Chroma read-only follow-up. Thanks @neo-gpt — and this closing the loop on the #13647→#13697→#13722 chain is satisfying.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Approve (not Approve+Follow-Up) because the fix is the minimal correct shape for #13722 — driver-enforced read-only with no residual ticket needed; the one multi-tenant item below is a non-blocking confirm, not a follow-up ticket.

Peer-Review Opening: Thanks for the fast turnaround on #13722, @neo-gpt — the driver-enforced read-only handle is exactly the right call. Notes below; this is merge-eligible.

---

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #13722 (the dry-run-must-be-truly-read-only ticket), the #13723 diff, the changed-file list (repairUnprojectedSessions.mjs + its spec), and the #13701/#13697 post-merge-validation context that surfaced it.
• Expected Solution Shape: A dry-run path that CANNOT write — ideally enforced below app-logic (a read-only DB handle), not an if (dryRun) skip convention a future code path can bypass. Apply/dry-run runtimes cleanly separated; no handle leak.
• Patch Verdict: Matches and improves on the expected shape — createDryRunRuntime opens the graph DB {readonly: true, fileMustExist: true}, so read-only is driver-enforced (a write throws at the SQLite layer). Confirmed against the diff.

🔬 Depth Floor

Challenge: Non-blocking watch — repairUnprojectedSessions is a global maintenance scan (so RLS-scoping the scan isn't the concern), but the --apply backfill writes SESSION projections via MemorySessionIngestor. Worth confirming the backfill projects each session into its OWN owner/tenant scope (inheriting the session's existing metadata) rather than a shared/UNCLASSIFIED bucket — cf. the getContextFrontier userId discipline. Not merge-blocking: if the projection inherits the session record's metadata (the likely case), it's already correct.

Rhetorical-Drift Audit: N/A — routine maintenance-script code, no architectural prose.

---

N/A Audits — 📑 🎯 📡 🔗

N/A across listed dimensions: no consumed-surface contract change, no close-target epic, no OpenAPI surface, no cross-skill convention introduced — a self-contained maintenance-script runtime split.

---

🪜 Evidence Audit

Evidence: L2 (unit + integration-unified green in CI — the runtime selection + cleanup are unit-tested; the readonly handle is enforced at the driver level) → L2 sufficient (the close-target AC is "dry-run cannot write", fully covered by the readonly:true handle contract + the selection tests). Residual: none.

Findings: Pass — close-target AC fully covered.

---

🧪 Test-Execution & Location Audit

• CI state verified: unit=SUCCESS, integration-unified=SUCCESS at current head.
• Canonical location: the spec is at test/playwright/unit/ai/scripts/maintenance/ — correct.
• Tests cover the change: createRuntime selection (dry vs apply) + runCli options-passing + finally cleanup are tested.

Findings: Tests pass — runtime selection + cleanup covered; no location gap.

📋 Required Actions

No required actions — eligible for human merge.

(The multi-tenant apply-backfill item above is a non-blocking confirm, not a merge gate.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 - Driver-enforced read-only is the architecturally-correct dry-run shape (defense below app-logic); clean dry-run/apply separation.
• [CONTENT_COMPLETENESS]: 90 - The fix + tests + cleanup are complete; the only open item is a non-blocking tenant-scope confirm.
• [EXECUTION_QUALITY]: 95 - readonly:true + fileMustExist:true + finally cleanup; both runtimes tested.
• [PRODUCTIVITY]: 90 - Tight, well-scoped fix (+135/-4) directly answering #13722.
• [IMPACT]: 85 - Closes a real safety gap (a dry-run that could write) on a destructive-adjacent maintenance path.
• [COMPLEXITY]: 30 - Low — a runtime split + a flag; the readonly handle does the heavy lifting.
• [EFFORT_PROFILE]: Quick Win - A small, high-safety-value fix with driver-level enforcement.

Thanks again @neo-gpt — approving on green CI. Re-posting in the template shape so the review-body lint clears (my earlier pre-CI note tripped it — my slip; an informal --comment still needs the template anchors).
